SPECIFICATION formng part of Letters Patent No. 392.039, date& ctobe'30, 1888.

Application filed. June 5, 1888.

Be it known that i, WILL'IAM J. LANE, of Poughkeepsie, in the County ofDutchess and 'State of New York, have invented a new and usefulImprovement in Steam-Engines; and I do hereby deelare that the followingis a full, clear, and exact description of the same.

Letters Patenta of the United. States were i granted to 'me November 2,1886, for an improvenent in .rer.olving-cylinler engines.

My present invention is a further improvement in the same class ofengines, but includes the leading features shown inny said patent.

l Tlesefeatures, in which my invcntion consists,

are details of construction, Whereby the better operation of theengineis secured,all as hereinafter explaincd, and as shown in theaccoinpanying drawings.

In the drawings, Figura l I'eprescnts in per spective my improved enginewith the upper partof the casing removed. Fig. 2 rcpresents ,the machinein plan view and with parts in horizontal section. Figs. 3 and tshowdetails enla'ged and in section. Fig. 5 represents the machine insection on a line x ;v of Fig. 2. Figs. 6 and 7 are enlarged views of"sections, showing the positions of the parts, the packing, and otherdetails. Fig. 8 is a central vertical section taken longitudinally ofthe aXis, but showing the journals and cne pisten in side elevation, thesection on one side being 'taken ccnt'ally of one shaft and the sectionon the opposite side centrally of the other shat't. Figs. 9; 10, ll, and'12 show on a larger scale, and more clearly., details of the partsshown in Fig. 8, Fig. 9 being a pcrspective view of ,thecylinder-bearing and the projection extending into the cylincler-hub,and Fig. 10 being a section on line y y of Fig. &and Fig. lla sec tionon line z z ol'Fig. 8. Fig. 13 represents a central longitudinal sectionof the hnbs, both ofthe cylinders, and the pisten-carrying wheel withpa'ts of the cylinder and wheel. Fg. la is a section on line y yo'f F-g.13.

The cylinders A-preferahly four in nunber-are set -adially on a -hubwhich turns with a shaft, B. A disk, C, is lmounted on another shaft,D,-set out of line with the first, and to this disk are attached theconncctions with the pistons, whereby the relative noveu ment of pistonsand cylinders imparts a ro- Se'lal Ne. 276.142. (No model.)

to the disk which carries the pistons, these being connected.

Thecylinders take stean and exhanst through their hub and the whole isinclosed in a case,

-E, whereloy all the Working parts are lubricated( So far the generalform and conbina- I tary movement to both the cylinder-hubs and I tionsdescribed are the same as thoseshown in I ny'aforesaid patent; but inthe said patent the ports which adnit steam to the cylinders are in theface of the hub, which s ground to fit against a corresponding face inthe casing, 1

and a collar and spring are provideclto ;maintain the connection betweenthe two faces and. overcome the tendency to separate by reason i of thesteampressure. 'W hile thisconstruction is effective, some inconveniencearises in the running of the engine by reason of the care required toadjust the pressure of the springs,

and these, if not of sufcient power, would allow,'leakage, and, if toogreat, would work tight, and cause loss of power by frict'ion. To avoidthis inconveniencc and at the same time to provide a; permanentconnection perfectly steam-tight, with a minimum of friotion andself-adjusting, I reccss the hub ou the induction side, and fit'it toreceive a cylndrical projection, G, from 'the casing through lateralports i n which steam is adnittcd and exhausted directly into and -fromthe bottons of the cylinders. jection fits the cavity in the hub, theinconvenience, referred to, of the separation ofjthe parts or theirliability to bind, is wholly avoided. On each side of thecircunferential line of porte, in the cylindricalsurface of the prejection G.are peripheral g'ooves a, in which are segmcntal springpacking-rngs a', hearing upon the periphery of the cavity.

The diameter of the projeotion G is slightly less than the interordiameter of the recess in which it is fitted', and the spring packingrings, by reason of their elasticity, project slightly beyond theperiphery ot' the projection, hearing against the walls of the recess,

As the cylindrical surface of the pro make a connection practicallysteam-tight.

Two or more ot' these rings are arranged on ports, so'as to break jointsat their divided ends. Between the grooves oneach side of the ports' andbetween the exhaust and induction ports are set transversely to therings a' packing-strips b, fittcd into suitable eavities over springs,by means of which they are constantly prcssed outwardly, and are alsoselfadjusting to take up the wear, the rings and l each side of thecircumferential line of the\ strips thus forming paeking on all sides ofthe ports. a

Figs. 5 and 6 show plainly the main indnction-port d and the exhaust c.They also show 'the supplemental induction-port c',h ereinafterexplained, and in these figures the packingpieces b are represented inpairs interposcd between the ports.

Steam is taken through the pipe H and passage h in the projectionG, asshown in dotted lines in Fig. 2, to the inlet-port (l. The exhaust e isthrough the ha1f-circumference of the extension and by-passagcs f in theextension shown in Figs. 6, 7, and 8, into a space, f', between theextension and interier of the rccess of the hub, and thence throughby-passages i, through the hub, and thence into a passage, k, formed byannular groovesin each of the opposing faces of the cylinder-hub and thehub of the disk C. These annular grooves are shown at ir, Fig. S. Itwill be observed that these annular grooves do not coincide throughouttheir whole extent, for the reason that they are not concentric. Theyappear in their proper position in Figs. 13 and 14-, the latter figureshowing that they cross each other, forming at this point a cylindricalpassage in cross-section, so that they are always in connection at twopoints, 3 and 4, during the revolution of the disk and cylinders. Fromthe passage formed by these groovcs a passages Z' extendthrough thehubof the disk to a second'set of annular grooves, m, one in the hub ofthe disk and the other in the opposing faceof an'extension, D', i'orminga hearing for the shaft of the disk 0. These grooves being v concentricform an an nnlar chamber,asshown in Fig. 8. The shaft of the disk (1 issuported in bearings formed in an extension, D', provided witha disk,1), by which it may be seeured to the casing, the said disk also closingthe opening in said easing at this point.

The extension D', as shown in Fig. 8, isprovided with longitudinalchannels o o', l'ormed above and below the shaft, and to forma bearingfor the shalt a sleeve, O, is inserted in the extension with a series ofpcrforations, in the uppcr prrt of the slceve to allow for the properlubrication of the shal't by the sten passing through the channel 'll`hoehannels o o' are connect-ed at the end, ;s shown at n", the slecvcbeing less than the whole length of the extension l'or this purpose. Y\hearing provided with suitable paeking is nade in the end of theextension, as shown at p'. The passage o is in ninterrnptcdcommunication with the annnlar grooves in in the disk-hub. The steanafter passing through the passages o o' cscapes into the casing throughport 17, Fig. 8.

Lubrication ol' the shaft of the eylindcr is cffected in a similarmanner. Steam from the space between the projcction G and the bottom ofthe reccsss in which itislocatcd passes into the passage 0, and thcncearound the end of the shaft into passage 0 and thence through .port p'into' the casing. It lubricatcs the shaft of the cylinders through holesin the hearing, as beibre' explained in connection with the 'shaft D. Inorder to provide for carrying steam when required, asin doing heavy workor in starting the engine, I arrange a snpplemental stean-induetion portin connection with a passage, h, and this is shown at e' in position foropera-` tion. It is located a little in front of the maininduction-port, at such distance thatit will be in communication withthe port leading to one of the cylinders when the main inductionport isbetween the port of that cylindcr and the one next following. Thepassage c' is in communication with the main steam-supply pipe throughthe stop-cock 2, so that when at work steam may be cnt off atthe mostecononical point or be allowed to' follow later at will. After theengine has been started this valveshonld under ordinary conditions bekept closed.

I have also in the present invention improved thc connection between thecylinders and the disk which carries the pistons, whereby I secure along and firmer hearing, better adaptedto maintain the parts in theirproper relative position, and atthe same time provide i'or the perfectand automatic lubrication of the connections. This connection, insteadof being arrangcd between the cylinder and the pistondisk, in whichposition but ashort hearing could be Secured, is in the present casearrangcd eentrall y upon one side of the cylinders. lt consists of acrank, L, provided with a pin, 3, which works in hearings formed in aboss on the side ol' the cylinders, and a pin, 4, in the other end,proiccting in an opposite direction, earries a ball, 5, on its end,which works in a socket l'ormcd in the disk C, and by a cap, 14,covering the same. In order to lubricate the pin 3, a passage, G, isbored 'down diagonally through thc hearing in the boss to intcrsect withanother passage, 7, bored directly from the outside to the interior ofthe cylindcr and within the onter limit of the pisten movement. The hole7 is plugged on the outside, and this leaves a passage from the interierof the cylinder to the hearing of in thc'cyliuder by reason of theintroduction of steam the steam is adnittcd to the hearing of the pinbefore the exhaust begins. The ball and socket are lnbricated by meansof a passage, which opens into an annnlar groovc, in the disk (l, formedas in Fig. 8,

and adapted to catch the water of condensa- 'the pin 3, so that everytime the pisten rises ees te v tion and oihand by the ccntrifngal `forcecause grooveand thence into the Channels q.

u ;make the conneotions at the point of contact praotically,frictionless. For this purpose I :make the connection between the pistenand the wrist pin on the disk of tuhuiar form, as `.shown more'ciearlyinFig. 3at 9. The direct e -.yconnection to the piston is formed by aheini- `spherica1 head, 8, secnred hy an extension to the tubular part9.

The under surface of the head 8 is plain and ;bear's at its center uponthe apex of a steel plate, e', fitted to a recess in the head of the.piston, 'its upper 'face being cone-shaped, as "shown, and thisConstruction is such as to sup- -.'-..portt`he head 8, but at the sametime to offer the best contact-surface. fhile running at ordinaryspeeds, the centri'fugal force of the ,Episton is at alltinessufificient to keep the head go aand plate v in contact and thepisten in proper position in relation to the pisten-connection., lontwhen stopping or starting or when running slowly that is not the case. I

` therefore arrange within an internally-screwthreaded cup, lei, in thepisten-head the concave hearing 13, conforrning to the shape of theother end of the tib cient to allow the necessary lateralsw ing tothe':the head 8, securing said' bea ring by a screw, 13 Under ordinarycircumstances or when the engine is running rapidiy there is noconftrifugal force keep the istons out. The heeh' of the head 8 is madeinclineyi to allow space between it and the hearing;,so as to permitfreemovement and to pel-mit of'the cntrance of steam for the pnrposeshflnbrication. To

S) is bolted a loop,

i 10, This loop embracsablock, 11, i'orrned as a. part of the studfl%and Secured to the i disk by a nut. This bolt passcs through sleeves23, as shown nore cia l-y in Fig. 1, to form a firm support forthepistons to work against. The sides of tlc block 11 are inclined, andthe oute' end is fornicd on a cnrve sti-uck from the lower edge where"it bears upon the plug, and this npper cui'ved end moves under thecnrved end of the ioop. Theinclined surface of the bottom and sidesjofthe block a're suffilink as the disk and, .cyiindens revolve: The uppercurved sirfacc is not in contact except under the conditions Inentionedin connection with the head 8 and hearing 13. On thesbaft is fixed agear, 15, meshing into another gearwheel, 16, on the counter-shaft,thelatter havin'g a pulley, 17, which, through abelt connected toanother pnlley which 'operatesthe governiig apparatus, is showat X, Fig.2.

tact at this poi nt, as the steanp mssn re and ccn y The counter-shah:is shown in Fig. i, and is of special construction. It is tubular inform, marked t, and it fits over a stern, u, provided with asteam-passage opening into the interier of the tuhnlar shat. Thispassage leads into the chamber which contains the working parte of theengine, whence exhaust steam maybe derived to lubricate the hearing ofthe hollow Shaft. The described arrangeent or'lnbrt cating the shaft itis ohvions he appiied to compound engines with eqnali'y as good results.

It Will be uuderstood that a lubricator-cup is attachcd to the engine atany convenient point, in connection with the Steaua-space, and thelubricant is thus carricd hy the steam to the different part-s to belnbricated, as above I described.
